ALL-SOLID-STATE BATTERY COMPRISING LITHIUM STORAGE LAYER HAVING MULTILAYER STRUCTURE AND METHOD OF MANUFACTURING SAME

An all-solid-state battery includes: an anode current collector; a lithium storage layer including a first layer located at an electrolyte-layer side and a second layer located at an anode current collector side, having a higher porosity than the first layer, and including an interface portion and a core portion, which is a remaining portion other than the interface portion; an electrolyte layer; and a cathode layer, wherein the anode current collector, the lithium storage layer, the electrolyte layer, and the cathode layer are sequentially laminated, and the interface portion is in contact with the first layer and has a higher binder content per unit volume than the core portion.
